SDH技术及在光纤传输网络中的应用

Technology And Application Of SDH In Fiber Transferring Network

本文针对传统的PDH传输体制的缺陷,比较介绍了SDH传输体制的优点,通过SDH技术的光纤传输网络实例,说明了SDH具体的应用,并描述了下一代SDH传输体制的特点。

The paper first expounds the bugs of the traditional PDH transferring system, and tells the strongpoint of SDH transferring system. The concrete application of SDH is illuminated with examples of fiber transferring network, and the trait of the next SDH transferring system is described.
